Theyreoutl ^•Rubtaan resistance to Rubiaan. The reason is the mode

Times are tough for unwanted fungi when Rubigan invades their turf. Dollar spot (even fun-gicide resistant strains), large brown patch*, fusarium blight, stripe smut and pink or gray snow mold—these troublemakers get their walking papers, starting the day you hire Rubigan.

Prevents and cures. In addition to the flexibility Rubigan gives you to manage a disease prevention program, it provides effective curative action on dollar spot when applied at slightly higher rates.

Rapid leaf penetration. As a foliar-applied, quick-penetrating, locally systemic fun-gicide, Rubigan is absorbed almost immediately into leaf tissue. So it's not susceptible to washoff by rainfall or irriga-tion once the spray has dried on the leaf. While the spray is drying, the active Rubigan ingredient goes to work inside the plant to start protecting immediately against disease.

No resistance worries. The bad news for common and susceptible turf fungi started years ago with successful Rubigan E.U.P. usage throughout the United States. Susceptible fungi commonly found in turf just plain haven't been able to develop *See label for tank mixes under moderate to heavy disease pressure.

resistance to Rubigan. The reason is the mode of action Rubigan has—involving three or more sites of I inhibition. As a multi-site inhibitor, Rubigan simply attacks fungi at many different sites with a real tough active ingredient. This eases constant worries about resistance.

Longer-lasting control. Because Rubigan is a very active, concentrated fungicide with long-lasting residual action (up to 28 days on dollar spot), it allows longer intervals between sprayings. So you can reduce application trips, save on fuel and labor. Lower use rates also mean less storage and lower handling costs.

Excellent turfgrass safety. Rubigan is safe on all commonly grown perennial turfgrass species when used at recommended rates. Fact is, several university turfgrass researchers will tell you Rubigan is as good for your turf as it is devastating for the five major turf diseases it controls.

Poa annua growth regulating effect: Applications of Rubigan to turfgrass areas containing Poa annua (annual bluegrass) have demonstrated a growth regulating effect on this species. Under certain environmental conditions and cultural practices, Rubigan applications may gradually reduce Poa annua populations in treated areas. Users desiring more information regarding this aspect of activity from Rubigan should obtain the Rubigan Product Information Bulletin on Poa annua from Elanco

, Products Company or their Rubigan distributors

prior to use. Do not use Rubigan on turf-grass areas containing Poa annua until this Product Information Bulletin is read

and understood. Precautions: Applications of Rubigan to turfgrass areas containing Poa annua (annual bluegrass) may result in

1 the gradual reduction of this species from the turfgrass area. Cumulative dosages of 5 pounds of Rubigan 50W per acre or 2 ounces per 1,000 sq. ft. are usually necessary for this response to occur. If such a reduction or loss of Poa annua is not acceptable to the user, Rubigan can be used at the mini-mal label rate (0.2 oz. 50W/1.000 sq. ft.) or in alternating application with contact type fungicides.

TURF even within a city.

S y m p t o m s of in jury include turf under the dripline of trees and in open areas having a burnt orange color. When symptoms are s e e n , n u m e r o u s aphids (40 or more) may be seen on a single grass blade. Close examination of damaged turf is necessary be-cause the aphids are small. If left untreated, a heavy infestation can kill the turf. Little damage from this pest was seen in 1983.

Greenbug infestations may be controlled with liquid treatments of Dursban® (1 lb. Al/acre) or Di-azinon (2.5 lbs. Al/acre). If reim festation occurs following treat-m e n t wi th t h e s e insec t i c ides , I O r t h e n e (acephate) at labelled rates has been effective.

FALL (Sept.-Oct.) Chinchbug—In the northern U.S., I t h e s e c o n d g e n e r a t i o n of chinchbug is at peak numbers in i S e p t e m b e r . N y m p h s complete j their development to adults in late October. Most chinchbugs over-winter in the turf, but some to pro-tected areas before winter.

Generally, infestation levels at this time are not high enough to warrant the use of insecticides. ' Early fall rains and infection by a parasitic fungus usually provides sufficient suppression.

B i l l b u g — D u r i n g September , , b i l l b u g adul t s that developed from s u m m e r larvae are often seen wandering about on side-walks, driveways, or other paved sur faces . Be fore winter , these adults seek shelter in thatch, al-ong s i d e w a l k edges , or near f o u n d a t i o n s a n d o v e r w i n t e r t h e r e . H o w e v e r , many , if not most, overwinter in the turf.

Grubs—Most species of grubs are in the third of their three stages of development and are feeding ac-tively. When soil temperatures de-crease in late October the larvae burrow deep into the soil to over-winter. Severely cold winters have little effect on survival.

Treatments of existing grub in-festations can be accomplished as late as early- to mid-September

What makes the Cushman Turf-Care System worth the investment: Aerating, hauling, dumping, spraying, seeding,

spreading and top dressing — one vehicle does the work of a fleet of machines.

The exclusive Cushman pin dis-connect system lets you attach and remove acces-sories in minutes.

argue with: Here is a single

vehicle that can do the work of a half dozen machines, at a fraction of the cost.

Here is a complete set of turf-care accessories that can

be attached or removed in minutes.

Here is a groundskeeping system that's so simple,

and so well-crafted, your maintenance and repair time will become prac-tically non-existent.

Economics aside, though, there is an even stronger reason to invest in the Cushman System.

Results.

The Turf-Truckster™. Powered by a rugged 18 hp air-

cooled engine, the Cushman Turf-

Truckster has the stamina to survive years of constant use.

A 3-speed syncromesh transmis-sion, hydraulic brakes, heavy-duty suspension and a %-ton pay-load capacity are all stand-ard. And you can choose between a 3-wheel or 4-wheel design.

By itself, the Turf-Truckster is the industry's state-of-the-art work vehicle.

But team it up with any of the following accessories, and you have the makings of an efficient, economical turf-care system. The aerators.

Because you have two types of turf to aerate, Cushman makes two aerator attachments for your Turf-Truckster.

The Greensaver® is ideal for greens and other delicate areas. Interchange-able aerating drums let you select the precise degree of aeration needed Vi" cores for fast-growth seasons,

cores for slow-growth months, and deep-slicing

tines for summer hot spells.

For the rest of your grounds, simply att-ach the Quick Aera-tor to your Turf-

Truckster. It offers the same choice in

aeration tines as the Greensaver, but ^ covers a wide 46" swath. The dump boxes.

To haul fertilizer, dirt, sand and other supplies, choose our Short Box attachment handles 1500-lb. payloads, sits low to the ground for easy loading and can be hydraulically dumped right from

/ the driver's seat. •Outboard Marine Corporation I9K.V Al l rights reserved. CUT 4-2157

But for maximum versatility, you may prefer our Flatbed /Box attach-ment. It does everything the Short Box does, hut converts to a flatbed carrier just by removing the sides and tailgate. The sprayer.

Turf pros swear by this as the finest spraying machine they've ever used. And it's no wonder when you consider all you get:

Uniform spraying controlled by your vehicle's ground speed governor; a PTO-operated centrifugal pump; and your choice of either a 100-gal. tank with a 15' rear boom, or our new 150-gal. tank with a 21' rear boom.

Plus, you can add a versatile handgun attachment for fogging bushes and spraying trees. The spreader /seeder.

Mounted on either side of the two Cushman dump boxes, the Spreader/ Seeder attachment actually outper-forms units costing much more.

The spreading rate is regulated by your Turf-Truckster's ground speed governor. Even over irregular terrain, you get uniform spreading.

The corrosion-resistant hopper holds up to 300 pounds of material, and spreads it evenly across a swath up to 40 feet. The top dresser.

Just 3 pins connect the Top Dresser to your Turf-Truckster chassis, and you're ready to top dress up to 220 feet per minute.

Everything from rock salt to powdered fertilizer can be uniformly spread across a 31'/2" swath. , A free demonstration.

using standard grub insecticides and sufficient (one-half-inch or more) irrigation. Treatment after this time may or may not kill the grubs before they move deeper into the soil to overwinter. When-ever treatment is applied the grubs should be in the top one to two inches of soil.

Black Turfgrass Ataenius—By September, adults of the current generation begin to fly into pro-tected areas, such as golf course roughs, to overwinter. Larvae that have not completed develop-ment to adults before frost are killed.

Mole Crickets—Mole cricket

nymphs develop through the summer and most become adults by fall. However, recent studies in Florida show some egg laying con-tinues throughout the year.

Greenbug—Severe infesta-tions of greenbug have been known to occur as late as the first week of December. Areas having a history of infestation should be reexamined when mild tem-peratures extend late into the fall. Heavily-infested turf will not sur-vive through winter.

Late fall infestations may be controlled with the same insec-ticides used to control the pest during the summer. WT&T
